Ade Weiss's New Book

Big news on the QRP/homebrew literature front. One of the titans of the genre, Ade Weiss, has released another amazing book about our hobby. I really enjoyed Ade's first history of QRP, and, because it covers a more recent period (1968-1981), I think this new this one is even more interesting. I took a portion of it with me on the train yesterday (and will be doing the same for the rest of the week!) The book is a wonderful technical history. It is filled with interesting stories and with very illuminating schematics and technical discussions. Ade takes us through the exciting early days transistor transmitters and direct conversion receivers. There is a lot of discussion of the commercial rigs that we've come to know and love -- lots of HW8s and Argonauts. And Ade has made it all available as a free download! Thanks Ade!

Hubble Ultra Deep Field in 3D



This is about 2 years old, but somehow I missed it. It is really beautiful, and it helps keep things in perspective.

Winterfest!

Billy and I went to the Vienna Wireless Association's Winterfest hamfest yesterday. We had a great time and met many SolderSmoke fans. Above you can see me and Randy, N3UMW, the designer of our SolderSmoke logo. Thanks again Randy!
There's Charles, AI4OT. Charles bought a copy of the SolderSmoke book at last year's Winterfest. This year he dropped by to show us his tiny Steve Weber QRP rig in an Altoids tin. FB! And he was kind enough to talk-up the book, helping me make a few sales! Thanks Charles!

We managed to get rid of a bunch of junk, and only bought one item of new junk (a Hallicrafters S-38E receiver). And we got to show our friend (and aspiring homebrewer) John what a real hamfest is all about.

Thanks to the VWS for another great 'fest.

The ZL2BMI DSB Transceiver

Oh man, I've been a fan of this rig for many years. I first read about it in the pages of SPRAT. Today I stumbled across what appears to be an on-line version of the instruction booklet prepared by Eric Sears, ZL2BMI. Lots of lore in there. Lots of soul in this rig.

This site has three documents describing the rig. All three are a lot of fun: http://www.mightymessage.com/

Three cheers for Eric Sears! Hip-hip...

Two Workbenches and a Mini Solder Pot

KC9LIF's bench

Hi Bill,
FB...What a great addition to your work bench. Congrats, you will put it to good use! I remember that scope when I worked at the Nuclear Physics Research Department Cyclotron at Indiana University about 30 years ago. It was the top of the line and worked great!! I lucked out by getting a Techtronics 2213 60Mhz dual trace at a Hamfest for a great price a few years back. Luck like that comes to those that wait. I recently gave my work bench a face lift... BTW, the bench doesn't look that nice now...

Dino's bench

Bill -
Ray VK4ZW's "solder pot" idea is a good one....for another version check out Doug Hendrick's tech note at his Hendricks QRP site:

Congrats on the new scope! We have finally moved to our "place in the sun" and I had the opportunity to double the size of my workbench.

Fat Tubes-day!


I couldn't resist using that title. Stephen from the UK sent me this link to Jeff Duntemann's site about Compactron tubes. Many possibilities here. I think I have a 6T9 in my junk box. These are kind of like tube versions of ICs, but with the advantage of being understandable.
